Battery and Sleep mode

[andcraig]

Odd question.
Not really a problem, just something i've noticed.

If, as i do everyday, put my powerbook to sleep, then unplug it, when i wake it up it's always at 94 percent battery charge.
And i know that if its above 94 it won't recharge up to 100%

So..is there any reason why it automatically loses 6% charge no matter how short a time its out for?

I think it's probably a coincidence. FWIW, it will lose power from two main sources - the fans (if it was hot when you put it to sleep, these will stop eventually though) and powering the RAM (constant), neither of which use all that much.

Some USB devices also will drain the battery when it's sleeping. I charge my phone from my computer, and I can do that while I am traveling if my phone is out of juce. As far as chageing, the battery waffles between dischargeing slightly ~4-6% and chargeing back to 100%.

Have you re-calibrated you battery lately?
